Two US software firms are asking the European Commission to take action against Microsoft's new Vista operating system, the Wall Street Journal reported Thursday. Adobe Systems has told EU regulators that Microsoft should be banned from incorporating free competing software for reading and creating electronic documents with Vista, the paper said, quoting people familiar with the situation. Anti-virus software maker Symantec will send officials to Brussels next week to brief journalists about features of Vista that it has told EU regulators will undercut rival makers of computer security software, the paper said.
